Magnetic Cable Arrest Assembly for Slack and Pullout Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cables often have excess length, leading to slack that is unsightly and poses a risk of accidentally disconnecting devices, potentially causing damage.
Innovation Solution
A cable arrest device with a dock, base, and cap that secures the cable through a gate with adjustable dimensions, using magnetic elements and specific orientations to resist removal forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a cable is made longer to ensure sufficient length between devices, then the cable can reach between devices, but slack or loops are created which are unsightly and pose safety hazards
Solution Approach 1:
The patent extracts the harmful slack portion of the cable from the functional connection between devices. The cable arrest device captures and secures the excess cable length separately, allowing the cable to maintain sufficient length for connection while removing the hazardous slack loops from the operational space.
Solution Approach 2:
The cable arrest device acts as an intermediary element between the cable and the devices it connects. This mediator captures the excess cable length and provides a secure anchoring point, preventing the cable from becoming a hazard while maintaining the necessary connection length.
2Reliability
If cable is secured firmly to prevent accidental disconnection, then device connection stability is improved, but the device may become difficult to remove when needed
Solution Approach 1:
The cable arrest device incorporates dynamic characteristics through its ratcheting mechanism and reversible anchoring. The device provides strong securement in normal operation but allows controlled release when needed, transitioning between a firmly engaged state and a removable state based on operational requirements.
Solution Approach 2:
The device applies preliminary counter-action to prevent accidental disconnection by creating resistance to unintended cable movement. Simultaneously, it prepares for intentional removal by maintaining a controlled engagement mechanism that can be deliberately disengaged when needed.

AI summary
A cable arrest device for securing a cable includes a dock, a base removably coupled to the dock, a cap removably coupled to the base, and a gate formed between the base and cap, the gate having a dimension and being configured to receive the cable therethrough, wherein relative movement of the cap and the base adjusts the dimension of the gate.
